The Effect of Radially Varying MHD Heat and Mass Transfer on Peristaltic Flow of Williamson Fluid in a Vertical Annulus

In the present paper, we have investigated the influence of the effects of radially varying MHD and mass transfer on peristaltic flow of Williamson fluid model in a vertical annulus. The governing equations of Williamson fluid model are simplified using the assumptions of long wavelength and low Reynold's number. An approximated analytical solution has been derived for velocity field using Perturbation method. The expressions for pressure rise are calculated using numerical integration. The graphical results are presented to interpret various physical parameter
